To all whom it may concern.-

' Be it known that I, LAWRENCE E. Dani a,

citizen of the United States,- residin in the QnQss i-QtManha tan,ci y N w-. e kiin the county of New;oik1 ndstaa;a new. Yorkg'have invented certain new and useful Improvements in'Pipes, of which the followingris a specification.

his invention relates to and has for an object to provide an im roved pipe.

The object of this mv'enti on is pipe which will arrest the p ssage'o condensation from the pipe-bowl t ward the mouthpiece andwhich will also arrest the passage of saliva and condensed moisture from the mouthpiece into the bowl and rovide suitable means .for the detention oft e same after it has been, arrested.

In the drawings accompanyin and form'- in a part of this specification; igure' 1 is a si e v1ew,'partly in central section,.of a ipe embodying a form of my improvement. 1g.

2 is a erspective view of one of the 1parts detache in 'the present instance t at part which is-employedfor use in the passage directly leading from the bowl of the pipe; and

'bacco-receiving cavity 8, from which bowl Fig. 3 is a similar view of the part usedin the stem of the p'ge. k v The pipe owl (designated in a general way by 7) is shown as having the usual tothere projects a stem or stem-receiving portion 9, having a draft passage-way 10,. leading into a recess or chamber 11, into which the. stem 12 of the. pipe may be inserted. For the purpose of preventing saliva flowing from the chamber 11 into the passage 10 anupstanding tube 13 may be inserted in the I passage 10 and have its end projecting into the chamber 11, so that a considerable quantity of liquid or semiliquid matter mi ht ac- I cumulate without clogging up the dra t-passage or-findi'n access into the bqwl. The

. condensed smo e and stray particles of saliva running into the lower-portion of the stem will not only, clog and foul the draft-passa e, but upon running into the bowl proper of t e pipe will contaminate the tobacco which is within the bowl and prevent at times the ready burning of the tobacco. It will be seen b reference to Fig. 2 thatthe ends 14 1% of t e tube 13 are conoidal, which will permit their ready insertion and removal into assages of various diameters and will always nsure a, tight fit irrespective of the number of times'the tube maybe removed andinthe arrest and storage of fluids.

serted, and by. having each end tapered it I will be reversible, so that the userfneed not exercise any care as to which end he inserts afterhadl hadl h t ou for the p s s l:fth 4 ,7 having a raft+passage ortion e cpanded into a chamber 16. In the orm of pipe illustrated the end portion 17 of the stem enters the chamber 11, this being the most common mode at the present time to rovide-a of assembling the. bowl and stem in the form of pipe illustrated.

irhs m- S as .15, having its lowerhe lower portion of the chamber 16 may I be stopped by a removable dam 18, in the resent instance shoyvn in the form ofa aving side walls 19 adapted to pass u into the chamber 16 and engage the walls t ereof frictional contact. Other engagement maybe 'rovi'ded, but in-this form ofpipe "frictiona contact will be suflicient. The'cu or rather the dam portion 18 is provided with an upstanding pipe or tube 20, projecting up I into the chamber 16 a. considerable distance. This tube constitutes the draftchannel mulation of saliva or other moisture within the chamber 16 will be held from-passage i downwardly through the pipe.

most instances wil be suflicient to receive and retain moisture; but in case a large The cup in '80 throu h the chamber and dam, and any accuamount should be permitted to accumulate there will be no chance of its falling into the pipe-bowl until it has risen to a height sufiicient to passdown the tube 20; and the dam will alsoprevent liquid which has accumulated within the chamber 11 from passing up into the stem and so .gainingaccess to the It will be seen that-theend 21- mouthpiece. of the tube 20 nearly approaches the end22 of the tube 13, and thereby brid es over the space within the chamber, and t at the-end 23 of the tube 20 nearly approaches to the ortion of the cup'ma be provided with a urled head 25 to enalil of the cup. for the purpose of emptying the same of any accumulations and to permit the parts to be lpro erly cleansed'fromtime to time. The e The bottom e the ready removal a 25 may be of less-diameter than the inside diameter of the chamber 11,

whereit is normally located, so that it will not become foul by the condensed smoke and nicotin which will work up on the walls of the chamber 11. V

As a further guard for preventing the passage of saliva into the plpe the mouth iece (designated in a general Wayby 30) may ave the orifice 31 of the channel overhung by a lip 32 and have the usual depressions 33 34 for engagement by the teeth. The enlarged portion 35 rearward of the depression 34 will act as a guard to the orifice and in conjunction with the lip 32 'will prevent the tongue of the smoker coming against the orifice 31, so that saliva cannot find access to the orifice, and also the tongue will be held away from such orifice and burning will be prevented.

The parts for insertion into the channels of the pipe may be made out of some suitable material; but I have ascertained by experimentation that when made of aluminium the pipe is rendered especially sanitary, for the end and having its 0t stem ha a chambered portion at its lower end with such' end fitting into the end of the bowl member, of a cup member comprising a cylindrical lportion closed at one or end arranged to fit into the engaging end of the stem, the cup member ha an elongated tube extending from its clos end portion u ward beyon the cylindrical portion into t e chamber of the stem, the bore of the tube be' continued through the end portion of tfiecylindrical part.

2. In a ipe, the combination with the bowl mem br having its upper end chambered and the stem having its lower .end chambered and fitted into the bowl member, of an integral cup member com lindrical portion 19, having a and flange 25, whereby the member can be inserted in the lower end of the stem with the flange en agin the end portion thereof, the cup mem er a so having an integral tube extending upward from the parts beyond the cylindrical portion 19 and rovided with the bore 23 continuing througthe end portion 18, substantially as set forth.
